Hello Dear Aji,


Until now, scientists are still researching the influence of genetics on the pregnancy / birth of twins. Before discussing the pregnancy / birth of twins, you need to know that the process of fertilizing an egg by a sperm cell must occur before a woman becomes pregnant. In pregnancy / the birth of twins, based on the ongoing fertilization process, it can be divided into:

Monozygotic twins - also known as identical twins. One egg cell is fertilized by one sperm cell, but division occurs at the beginning of its development to form two embryos. Many scientists suspect that identical twins are influenced by genetic factors, namely genes involved in cell adhesion. This suspicion is still unconfirmed and requires further research
Dizygotic twins - or fraternal twins. Formed because two eggs are fertilized by different sperm cells in the same menstrual cycle. It is more common if there is a mother or sister with a history of twins. This condition is also caused by hyperovulation, which is the release of more than one egg in one menstrual cycle. Research on the specific genes that cause hyperovulation is still being investigated. Various other contributing factors are maternal age, ethnic background, diet, body composition, and the number of other children, as well as in vitro fertilization techniques.

Regarding your question about a gene called "birth weight gene" has not been proven to affect pregnancy / multiple births. Journals or scientific articles on this subject have yet to be found.


That's all I can say, hopefully it's useful
